June
An Irish surname probably meaning “the young one,” traditionally linked to French le Jeune.
The #8,103 most common surname in the United States (2010 Census) — about 1 in every 75,469 Americans shares it.
Etymology
The surname June is traditionally explained as a corruption of French le Jeune, meaning “the young” or “the younger.” In this view, it began as a descriptive nickname for a younger man, later becoming a hereditary surname in Ireland. The older source cited by Lower treats this as the most likely origin, and explicitly rejects any connection with the month name.
History
Lower says the name was already recorded in Ireland by the early 14th century. The surname appears to have been established as an Irish family name fairly early, and later English-language records preserve it in the shorter form June. Because the evidence is old and the spelling is simple, it is possible that some later bearers have unrelated origins, but the Irish derivation is the standard explanation in the historical dictionaries.
